Forest River XLR 27 pump issues

More than frustrated here guys, i have nothing but issues with this trailer since new. Its a 2013 and has a sureflow 4008 pump. Trailer works fine on city water but when i try running off the tank everything goes to pot. Its like its sucking air and constantly spits water it will never give a steady stream of water nor will it ever shut off. I have checked everything for leaks. I have been through all the trouble shooting of bleeding that air from the lines to making sure all the fittings are tight. I even replaced the line from the tank to the pump thinking there was a breach in the line somewhere. I am about out of options of things to check. It has been back to the stealership twice for this issue and comes back the same way it went in (of course they claim it worked fine for them though) and now is out of warranty. Any ideas would be greatly appreciated, if i do wind up replacing the pump should i go with a better pump or stick with the same one?
  • Pump is sucking air which can only happen on suction side of pump......
    Suction line from tank
    Suction side fittings
    Suction side strainer
    Suction side of pump casing


    Disconnect suction line from pump

    Install another section of line and sick in in a large bottle of water.
    Turn pump on.

    Same problem....then it the pump

    Sucks the water out/pumps OK...then problem is with suction line/fittings

    And when dealership said OK....it works.....did you have them show you?

    It may be out of 'warranty' but it is an on-going problem that was identified/worked on during warranty so should still be covered.
  • Yes checked the screen and the clear housing, ill have to give the a call tomorrow and see if they will do anything for me.
  • did you also check the inline filter housing for cracks and and make sure it's clean. I would call Shurflo - the pump will have its own warranty and I think it's 2 years. I had trouble with one and they sent me out a new one after my one year warranty with the trailer.
